Prikaz logotipa ali texta v sliki

Zanima me kako bi s php-jem sprogramiral da v sliki prikaže logotip spletne strani ali pa textovni URL od spletne strani?

Tu je ena slika za primer [z dodanimj (:SMEJ.SE:)]:


Trenutno za prikaz slik uporabljam naslednjo skripto:

[?php /* $Id$ */

ignore_user_abort();
set_time_limit( 0 );
error_reporting( FATAL | ERROR | WARNING );


ini_set( 'register_globals', '0' );
ob_start();

//while ( list( $key, $val ) = each( $HTTP_GET_VARS ) ) $_GET[ $key ] = $val;

if ( ! isset( $_GET['s'] ) ) die( 'Source image not specified' );
if ( isset( $_GET['w'] ) && ereg( "^[0-9]+$", $_GET['w'] ) ) $MAX_WIDTH = $_GET['w'];
else $MAX_WIDTH = 320;
if ( isset( $_GET['h'] ) && ereg( "^[0-9]+$", $_GET['h'] ) ) $MAX_HEIGHT = $_GET['h'];
else $MAX_HEIGHT = 200;

$src_size = getimagesize( $_GET['s'] );

if ( $src_size[0] > $MAX_WIDTH && $src_size[1] > $MAX_HEIGHT ) {
if ( $src_size[0] > $src_size[1] ) {
$dest_width = $MAX_WIDTH;
$dest_height = ( $src_size[1] * $MAX_WIDTH ) / $src_size[0];
}
else {
$dest_width = ( $src_size[0] * $MAX_HEIGHT ) / $src_size[1];
$dest_height = $MAX_HEIGHT;
}
}
else if ( $src_size[0] > $MAX_WIDTH ) {
$dest_width = $MAX_WIDTH;
$dest_height = ( $src_size[1] * $MAX_WIDTH ) / $src_size[0];
}
else if ( $src_size[1] > $MAX_HEIGHT ) {
$dest_width = ( $src_size[0] * $MAX_HEIGHT ) / $src_size[1];
$dest_height = $MAX_HEIGHT;
}
else {
$dest_width = $src_size[0];
$dest_height = $src_size[1];
}

if ( extension_loaded( 'gd' ) ) {
$ext = substr( $_GET['s'], strrpos( $_GET['s'], '.' ) + 1 );
if ( $ext == 'jpg' || $ext == 'jpeg' ) $src = imagecreatefromjpeg( $_GET['s'] ) or die( 'Cannot load input JPEG image' );
else if ( $ext == 'gif' ) $src = imagecreatefromgif( $_GET['s'] ) or die( 'Cannot load input GIF image' );
else if ( $ext == 'png' ) $src = imagecreatefrompng( $_GET['s'] ) or die( 'Cannot load input PNG image' );
else die( 'Unsupported source file format' );

$dest = imagecreatetruecolor( $dest_width, $dest_height ) or die( 'Cannot initialize new GD image stream' );
imagecopyresized( $dest, $src, 0, 0, 0, 0, $dest_width, $dest_height, $src_size[0], $src_size[1] );
if ( imagetypes() & IMG_PNG ) {
header ( 'Content-type: image/png' );
imagepng( $dest );
}
else if ( imagetypes() & IMG_JPG ) {
header ( 'Content-type: image/jpeg' );
imagejpeg( $dest );
}
else if ( imagetypes() & IMG_GIF ) {
header ( 'Content-type: image/gif' );
imagegif( $dest );
}
else print 'Cannot find a suitable output format';
}
else print 'GD-library support is not available';

ob_end_flush();

imagedestroy();

Hvala vnaprej!

Za logotip uporabi imagecopy, imagecopymerge; za pisanje po sliki pa so funkcije imagestring, imagefttext, imagettftext...
